Achieve pt total glitch?
Did you transfer or faction change/name change your toon in the past?
You'll note, for instance, that if you click on your Dungeon and Raid achievement tab on the armory, and click (for example) Classic Dungeonmaster, it will show up as unearned despite the fact that every single criteria for it is checked off.
Similarly, any achievements not earned on the character you're posting on (as in Malahierba's case) will not count towards that character's armory-displayed total unless you log in and uncheck the option.
TL;DR: it's a choice between privacy and brag rights.
